摘要: 本文建立了固相聚合酶链反应(PCR)技术检测恶性疟原虫的方法,并对培养的FCCl/HN株及西双版纳恶性疟患者进行检测,结果表明该法对FCCl/HN株DNA敏感到0.2pg,相当于10个疟原虫,对西双版纳疟疾患者检测恶性疟30例,间日疟4例,证实PCR仅特异扩增恶性疟原虫DNA。提示固相PCR是早期、敏感、特异检测恶性疟原虫的方法。

Abstract: Solid phase PCR for detecting Plasmodium falciparum was established and used to detect cultured FCCl/HN isolate and malaria patients in Yunnan Province.The results revealed that the sensitivity of the method for detecting FCCl/HN isolate DNA was as minimal as 0.2 pg,or about 10 parasites. The specificity of the method was confirmed by discriminating malaria patients infected with different species of Plasmodium .The results suggest that solid phase PCR is a specific and sensitive method for early detection of P.falciparum.
